Now, i'm doing the experiment with opencv to stitch several images into a panorame, but These pictures are taken at different angles. now i want to do is to project all the images onto a cylindrical surface, then using the SIFT to match the features to get the transform matrix. how should I do it? is there any interface of opencv to do that(to project all the images onto a cylindrical surface, and i don't know any parameter of the camera)?

In the OpenCV sample folder there is a script called stitching_detailed.cpp. It does the whole pipeline for creating panoramas including feature extraction, matching, warping and blending, etc.
You should have a look on it: https://github.com/Itseez/opencv/blob/master/samples/cpp/stitching_detailed.cpp

You can set it with the flag `warp`. E.g. `--warp=cylindrical`. – Kornel Aug 08 '14 at 06:11
